Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551012, here are decompositions:

19 + 550993 = 551012
43 + 550969 = 551012
61 + 550951 = 551012
73 + 550939 = 551012
103 + 550909 = 551012
109 + 550903 = 551012
151 + 550861 = 551012
181 + 550831 = 551012

Showing the first eight; more decompositions exist.
